求教GWD 4-40 （作assumption总是云山雾罩）

Many people suffer an allergic reaction to certain sulfites, including those that are commonly added to wine as preservatives.  However, since there are several wine makers who add sulfites to none of the wines they produce, people who would like to drink wine but are allergic to sulfites can drink wines produced by these wine makers without risking an allergic reaction to sulfites.

A.        These wine makers have been able to duplicate the preservative effect produced by adding sulfites by means that do not involve adding any potentially allergenic substances to their wine.反前提

B.        Not all forms of sulfite are equally likely to produce the allergic reactions.横向比较无关。

C.        Wine is the only beverage to which sulfites are commonly added.无关

D.       Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction.范围扩大

E.        Sulfites are not naturally present in the wines produced by these wine makers in amounts large enough to produce an allergic reaction in someone who drinks these wines.

确实是E啊  我做的时候读到D觉得有点象

但是读完E之后就觉得肯定是E了

把assumption 当成support 题做 , 哪个能加强结论就是答案 , 个人觉得很有效

E 选项说这些葡萄酒中不会自然的产生Sulfites   , 不是对结论people who would like to drink wine but are allergic to sulfites can drink wines produced by these wine makers without risking an allergic reaction to sulfites加强了吗.
